Our owners have 30 years of health and fitness industry experience in San Francisco.
We've managed small studios, worked at large gyms, run diverse fitness programs, and found success as trainers, coaches, and athletes. 


Shannon Boughn, Studio Co-Owner
Lead Instructor & Motivator

Shannon has curly hair and sometimes doesn't look in the mirror before she leaves the house. The effect can be startling, especially when she is barking out instructions on the bike. She has not had a baby, much to everyone's relief. She may someday reproduce through mitosis.

Favorite Part of the Brain: Amygdala
Favorite Parent: ummm...I like them both the same but in different ways?
Favorite Exercise: squats


Marissa Axell, Studio Co-Owner
Director, Fitness & Media

Marissa--yikes!  She races bikes and sometimes crashes them. Repeated falls have not mellowed her out. Her classes are thoroughly engaging. We voted her least likely to need a microphone when teaching.

Favorite Drink: Kombucha tea. She sometimes just drinks it directly from the compost bucket.
Favorite Person: her cat
Favorite Exercise: cycling

Thandi looks like a nice person. Then you take her class and you think, why would a nice person make me suffer like this?  Thandi's TRX and Circuit classes are fun to take and funnerer to watch other people take while you sip coffee.

Favorite Muppet: Camilla the Chicken
Favorite Person: Camilla the Chicken
Favorite Exercise: anything where she's upside-down


Robyn somehow manages to look stylish even when she's sweatier than one of those women on Glow taking a Bikram yoga class. We kinda resent her.

Favorite Cheese: cubed
Favorite Person: Shannon (she's reading this, right?)
Favorite Exercise: TRX


Alexis is tough. She has done more Ironmans than your mom. She recently had a baby which I hear is kind of hard. She is also a kick-ass cycle instructor who will blah blah, something inspiring.

Favorite Food: Donuts
Favorite Person: Shannon
Favorite Exercise: running

Chelsea is tall and strong. She will harness the power of her tallness to make you strong, too. 

Favorite Color: black until they come up with something darker
Favorite Person: strangely, also Shannon
Favorite Exercise: not swimming


Armando (not pictured) is a man. You will recognize him because he is a man. The rest of us are not.

Favorite thing: long walks on the beach
Favorite Person: Marissa, because I feel sorry for her
Favorite Exercise: Capoeira 


Maisie is another athlete who went off the rails and had kids. Her bike now sits unloved and unridden but her children are fed. She has a lot of pent-up energy that she would like to share with you. She is a triathlete who was a rower in college. She was also captain of the softball team. She is married to a man, go figure.

Favorite TV Show: she claims not to watch TV and tried to tell me her favorite author.  I ignored her.
Favorite Person: someone named Brewster; it sounds made up
Favorite Exercise: bootcamp

Angela teaches everything: She teaches strength, cycle, TRX (here), and woodworking (not here). 

Favorite TV Show: American Pickers
Favorite Person: Shannon, obvi
Favorite Exercise: planks (get it?)


Katy used to dominate the four-square game in grade school. So while it may seem like she’s offering the gentlest classes at this place, beware: behind her sweet smile lurks a fierce competitor. She’s taught yoga for a long time, practiced for longer, and she's trained with some of the most creative and dedicated folks around. In addition to teaching here at 17th Street, she works one-on-one with students at her private studio around the corner.

Favorite Person: She's new, but thinks it will soon be Shannon
Favorite Exercise: Doesn’t understand this question ;)
Favorite New Place: Owens Valley, CA
